The new plastic idea thus correctly represents actual aesthetic relationships. To the modern artist, it is a natural consequence of all the plastic ideas of the past. This is particularly true of painting, which is the art least bound to contingencies. The picture can be a pure reflection of life in its deepest essence.

The development of plastic art is determined by the will to visualize. Art of the past represented the subjective vision of 'naturalistic relationships'. Neoplasticism embodies a subjective vision of 'plastic' relationships.. .Pure thought, which does not signify a concept derived from natural phenomena but which is contained in numbers, measures, relationships and abstract lines, is revealed conceptually (as Reason) by Chinese, Greek and German philosophy, and aesthetically by contemporary Neoplasticism [= De Stijl.

However, new plasticism is pure painting [in contrast with the opinion of Theo van Doesburg, then]: the means of expression still are form and color, though these are completely interiorized; the straight line and flat color remain purely pictorial means of expression.

In terms of composition the new plasticism is dualistic. Through the exact reconstruction of cosmic relations it is a direct expression of the universal; by its rhythm, by the material reality of its plastic form, it expresses the artist's individual subjectivity. It thus unfolds before us a whole world of universal beauty without thereby renouncing the human element.

Space and time are the only forms on which life is built and hence art must be constructed... The realisation of our perceptions of the world in the forms of space and time is the only aim of our pictorial and plastic art... We renounce the thousand-year-old delusion in art that held the static rhythms as the only elements of the plastic and pictorial arts. We affirm in these arts a new element, the kinetic rhythms as the basic forms of our perception of real time.

The plasticity idea «form draws form», expressed by Vladimir Sterligov in the late 60s of the last century, is being honed in lithographs. This is an attempt to find inseparable plastic penetrations of depicted forms. An attempt to ensure that one detail of a drawing becomes part of another. Flowing into each other, they should make a strong visual composition. The main task is to create a single graphic organism, when a drawn object gives life to another one. In this case, there is an interpenetration of silhouettes, where the foreground, middle ground, and background become a single whole. Light, transparent drawing, on the one hand, and a found plastic construction, on the other hand, the way I see it, complement each other, making a graphic sheet both airy and convincing.

And then, as you can see, I give greater and greater importance to the materials I use in my work [c. 1936]. A rich and vigorous material seems necessary to me in order to give the viewer that smack in the face that must happen before reflection intervenes. In this way, poetry is expressed through a plastic medium, and it speaks its own language.

The new plastic idea cannot, therefore, take the form of a natural or concrete representation, although the latter does always indicate the universal to a degree, or at least conceals it within.

In my own researches and findings I have always insisted on plastic and sculptural values, and also on what I call a poetic climate. The object, whether it is a book, a bottle, or a human body, once it is visualized and expressed by means of clay, stone, or wood, ceases to be a document and becomes an animated object in stone, wood, or bronze and lives its independent life..

This new plastic idea will ignore the particulars of appearance, that is to say, natural form and color. On the contrary, it should find its expression in the abstraction of form and color, that is to say, in the straight line and the clearly defined primary color.

A painter makes patterns with shapes and colours, a poet with words. A painting may embody an ‘idea’, but the idea is usually commonplace and unimportant. In poetry, ideas count for a good deal more; but, [...] the importance of ideas in poetry is habitually exaggerated: '... Poetry is not the thing said but a way of saying it.' [In poetry,] the poverty of the ideas seems hardly to affect the beauty of the verbal pattern.

The plastic expression of space is inconceivable without light. Light and space complete one another. In architecture light represents an element of plastic expression – in fact, the most important one. An organic relationship between 'space' and 'material' is possible only with the aid of light. The highest achievements in architecture can be accomplished only if light also is treated as plastic form.

Geometry is to the plastic arts what grammar is to the art of the writer.

A particular thought is not the same as a concentrated, creative thought, which is actually a feeling of inward-looking calm. The former produces a descriptive and morpho-plastic art, the latter a purely plastic manifestation. It is a question of the universal versus the individual.
